KISSIMMEE, Fla. -- Minor League shortstop Carlos Correa, MLB.com's No. 2-ranked Astros player, has made such a positive impression in his first Spring Training that Astros general manager Jeff Luhnow said he expects him to spend most of the season with Class A Quad Cities of the Midwest League.

Correa, last year's No. 1 overall Draft pick, is in Minor League camp, but he appeared in a Grapefruit League game Saturday in Viera, Fla., and went 1-for-2 with an RBI single, a run scored and a stolen base. The 18-year-old carries himself with the poise of polished pro.

Luhnow said Correa could begin the year at extended spring training, but will wind up in Quad Cities soon. Last year, Correa hit .232 with two homers and nine RBIs in 39 games with the Gulf Coast League Astros before hitting .371 in 11 games at Greeneville.

"A lot of players I've had experience with that have moved quickly, that first full season, especially if you're a high school player in low A, it's a very good, challenging place to start," Luhnow said.

Quad Cities, which is in Davenport, Iowa, is in its first year as an Astros affiliate, but it was associated with the Cardinals when Luhnow was in charge of St. Louis' farm system. He said he's sent players there to start the season when snow's been on the ground, which isn't ideal.

"We'll have to weigh that part of it," Luhnow said. "He's certainly making a case for maybe even a level higher. We're going to take the conservative approach with him."

Luhnow said he was impressed by how Correa, first baseman Jonathan Singleton -- the club's top prospect -- and right fielder Domingo Santana went about their business when they suited up with the Astros on Saturday.

"They all three looked like they fit in right out of the gate, and that's amazing," Luhnow said. "Obviously, a Spring Training game is very different than a big league game, but it was under the lights and it was against some pretty good pitching and it was a close game. I think Astros fans should be very excited about what was there."
